Answer:
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
30% = 30/100 = 30 ÷ 100 = 0.3.
100% = 100/100 = 100 ÷ 100 = 1.
Increase the number by 30% of its value.
Calculate the New Value
New value =
12 + Percentage increase =
12 + (30% × 12) =
12 + 30% × 12 =
(1 + 30%) × 12 =
(100% + 30%) × 12 =
130% × 12 =
130 ÷ 100 × 12 =
130 × 12 ÷ 100 =
1,560 ÷ 100 =
15.6
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 12 =
15.6 - 12 =
3.6

Answer:
4x-6y-12=0 than it passes through the origin so.distance equals /ax+by+c/all over a^2+ b^2= 4(0)+6(0)-12/4^2+6^2= -12/16+36=12/52=0.23077
The formula for perimeter is
Side a x2 + side b x2
So just multiply 18 by two, and subtract it from 108

Answer:
A x = 3
Step-by-step explanation:
A = ½θR²
R = x
x = √(2Α/θ)
θ = (360 - 60)(π/180) = 5π/3 radians
x = √(2(15π/2) / (5π/3))
x = √(15π(3/5π))
x = √9
x = 3
